Step by step guides

In the following guides example IPs, users, sites and passwords are used. You will have to exchange the IP addresses and sites to your own. Passwords used in these examples are not recommended for real life use. Passwords and keys should be chosen so that they are impossible to guess or find out by eg a dictionary attack.

In these guides for example Firewall->Userswill mean that Firewall first should be selected from the menu at the top of the screen,

and than the Users button to the left of the screen.
